chained_bear commented on the word archil
"Another important red dyestuff was archil, or orchil, a dye made from lichens found on coastal rocks. Well known in classical times, it persisted in the Middle East for many centuries. In 1300, a Florentine merchant rediscovered the formula and consequently did a booming business exporting red cloth. Like brazilwood, however, archil tended to fade, a serious disadvantage for many buyers."
